Hah bike-for-house a common ailment then. (and drums and synths it seems)
In my case I needed a deposit for a tenancy which is even more pathetic. It left me with enough afterwards to try a modern 'serious bike' so I bought an R1100S - it was very fast and very top heavy what with the generator sat on top of the engine, fuel tank after that, and I am hardly built for rugby, nor basketball. That was sold to actually buy a house and I wasn't sorry to see it go!
Had a whizz round on the CB750F1 this evening down to Oxford n back. The throttle despite quite a bit of cleaning of the cables and mechanism (smooth operation now) seems very stiff. Hand achingly so, it is hard to set the revs at low speed.
